F in A (→FC), literal reading

When interpreted literally, the chord on the 3rd beat of the bar in A (→FC) consists of the following notes: F1-F-b-d1-f1, which, in turn, results in a G major chord (F major), which could be a part of this harmonic sequence. However, Chopin would generally avoid such an unnatural orthography; therefore, he most probably overlooked here the naturals lowering all f notes to f. They were added both in FE (→EE) and GE, and the composer did not question the printed naturals in any of the three teaching copies containing annotations coming from him.

b. 8

composition: Op. 28 No. 9, Prelude in E major

..

In A (→FC,FE→EE1) and CGS there is no  lowering b to b. Chopin's mistake, obvious in this context, was corrected in GE and EE2. The fact that Chopin was convinced of the presence of b in the preceding part of the bar is evidenced by the naturals written in A before B1 and b on the 4th beat of the bar.

b. 9-13

composition: Op. 25 No 9, Etude in G♭ major

..

In GC (→GE1), FE and EE there are no naturals raising c to c in bars 9 and 13 and c1 to c1 in bar 12. These are Chopin's obvious oversights, while the signs were added in FED (in bar 9) and FEJ and FES (all).
GE1 also omitted the  raising c1 to c1 in bar 10. GE2 (→GE3) features the correct text.

b. 9

composition: Op. 28 No. 10, Prelude in C♯ minor

..

In A (→FC,FE) there is no  lowering d2 to d2. The Chopinesque inaccuracy was corrected in EE and GE.

b. 11

composition: Op. 25 No 11, Etude in A minor

..

In the 2nd half of the bar, the only accidental in the part of the R.H. in GC, FE and EE1 is a  raising d3 to d3. The notation, although inaccurate, determines also the sound of the 6th and 10th semiquavers in the 2nd half of the bar as d2 and d1. In turn, nothing indicates raising the 3rd, 7th and 11th semiquavers, which, in this situation, should read f3, f2 and f1. This version, however, is impossible in this melodic and harmonic context – the use of g as delay of the fifth of the B7 chord requires f (possibly f) as resolution. The sharps raising the discussed notes to f3, f2 and f1 were added in GE and later EE (in EE2 without  before the 11th semiquaver). Cf. bar 75.
